研究了己醇、辛醇、癸醇和月桂醇对丙酸十二铵(DAP)-四氯化碳反胶束溶液增溶水和氯化钠水溶液的影响。在DAP浓度固定时,水增溶量对醇浓度的关系出现极大值,在醇浓度相同时,长碳链醇较短碳链醇有更大的增溶水能力。在固定DAP浓度和增溶水量最大时,氯化钠的存在将导致水溶液增溶量的显著下降。乙酸十二铵(DAA)、DAP和丁酸十二铵(DAB)的四氯化碳溶液对氯化钠水溶液的增溶量随氯化钠浓度的升高而有不同的走向,DAA增溶量逐渐升高,DAP先升高后下降,并出现最大值,而DAB则单调下降。
The effects of hexanol, octanol, decanol and lauryl alcohol on the solubilization of sodium dodecyl propionate (DAP) -carbon tetrachloride reverse micellar solution and aqueous sodium chloride solution were studied. When the concentration of DAP is fixed, the relationship between the amount of water solubilization and the concentration of alcohol shows a maximum. When the concentration of DAP is the same, the long-chain alcohol has a greater ability to solubilize water than the short-chain alcohol. The presence of sodium chloride will result in a significant drop in solubilization of the aqueous solution at the maximum fixed DAP concentration and maximum amount of solubilized water. The solubilities of sodium dodecyl sulfate (DAA), DAP and DAB in carbon tetrachloride solution with different concentrations of sodium chloride increased with the increase of sodium chloride concentration. DAA solubilization The amount of DAP increased first and then decreased, and the maximum appeared, while DAB decreased monotonically.
